Border control: Study shows how proteins permit entry to a cell

The means by which proteins provide a ‘border control’ service, allowing cells to take up chemicals and substances from their surroundings, whilst keeping others out, is revealed in unprecedented molecular detail for the first time today (16 October) in Science Express.

Scientists identify a molecule that coordinates the movement of cells

Even cells commute. To get from their birthplace to their work site, they sequentially attach to and detach from an elaborate track of exceptionally strong proteins known as the extracellular matrix. Now, in research to appear in the October 3 issue of Cell, scientists at the Howard Hughes Medical Institute and Rockefeller University show that a molecule, called ACF7, helps regulate and power this movement from the inside – findings that could have implications for understanding how cancer cells metastasize.
